IMPROVEMENT IN BARBED FENCE-WIRES.

Specification {forming part of Letters Patent No. 199,924, datedFebruary 5, 1878; application filed July 25, 1877.

To all whom it may concern:

Be it known that I, MONTRAVILLE P. MIGHELL, of Delta, in the county ofKeokuk and State of Iowa, have invented certain Improvements inBarbedFence-Wires, of which the following is a specification:

My invention relates to that class of fences which are constructed ofwire and provided I with metal points or barbs; and the improvementconsists in forming each of the finished strands of two or more smallerstrands twisted together, one of which latter is cut at intervals, andhas its ends bent or turned out-- ward to form barbs, as hereinaftermore fully explained.

In the drawings, Figure 1 represents a short section of a wire. composedof three strands,

previous to bending out the ends of the severed strands, and Fig. 2represents two finished wires, composed, respectively, of three and twostrands.

The object of this invention is to'produce a barbed wire which may beproduced by machinery cheaply and rapidly, and one from which the barbsare not liable to become detached or loose.

To accomplish these objects I twist together two or more strands of wireof proper size and cut or severed, the ends of the wire or strand a arebent outward, as shown in dotted lines in Fig. 1, and further shown inFig. 2. This forms the points or barbs 0, which can be made to stand atany angle, and project from all sides of the wire A, by cutting orsevering the same, as

weakened in forming the barbs as where but two are used.

In cutting the strand which forms the -barbs care should be taken thatthe same strand is out each time, in order that the strength of theremaining strands may remain unimpaired.

The strands being tightly twisted together, it will be seen that it isimpossible for the barbs or points 0 to become loose or detached. 7

The strands can be very rapidly and evenly twisted together bymachinery, and the strand a may be readily cut and bent outward, thusrendering the construction of the finished wire very simple and cheap. k

I am aware that wire barbs have been wound upon fence-wires in variousforms, and that said wires have been bent at the points where the barbsare located to retain the barbs in place; and such construction I do notclaim.

Having thus described my invention, what I claim is l. A barbedfence-wire consisting of one or more unbroken strands, having acontinuous spiral twist or curvature, and additional short strands atwisted tightly into the curves or sinuosities of the main strand, andbent outward at their ends, substantially as shown and described.

2. The herein-described method of forming barbed fence-wire by twistingtwo or more strands together, and subsequently severing one of saidstrands at suitable intervals, and bending the ends formed therebyoutward.
